Moisture Mapping Determining Acceptable Moisture Levels

Moisture mapping plays a crucial role in assessing the health of buildings and preventing moisture-related issues. Understanding acceptable moisture levels is essential to ensure a healthy indoor environment.

What is an Acceptable Damp Reading?

Damp readings are measured using a moisture meter and indicate the amount of moisture present in a material or surface. Acceptable damp readings vary depending on the material and environment in question.

  • Concrete slabs: Less than 75% relative humidity or 3% moisture content
  • Wood framing: Less than 19% moisture content
  • Drywall: Less than 16% moisture content

These limits help determine if a material is excessively damp and at risk of moisture damage, mold growth, or structural issues. It’s important to consult with a professional to determine the specific acceptable damp readings for the materials and conditions in your specific building.
